1. Removal of shingles
ANS estimate for the actual number of squares (not squarefeet). No estimating
or rounding
2. Replacement of shingles
ANS a) Include waste in the calculation
-10% - Composite
-15% - wood
b) Round up to the nearest bundle
-Assume 3 bundles per SQ for composite shingles
-Assume 4 bundles per SQ for wood
3. What do wood shingle estimates always end with
ANS fourths. .25, .5, .75, .00
4. What do composite shingle estimates always end with
ANS thirds. .33, .66, .00

,5. Calculating Hip Roofs
ANS get main body first. extensions second.
6. Hip roof triangular ends
ANS are calculated when the main roof is calculated b/ca triangle is accounted
for that didn't actually exist
7. When calculating extensions on a hip roof
ANS don't count for the triangle, butdon't forget the two parrallelograms
remaining (there is a good chance they are identical)
8. When calculating the main body
ANS Don't assume that you can just find one sideof a roof and double it. Why?
the rafters might be different lengths

, 9. How do you find the height of a hip roof
ANS the height of the triangle is equalto the length of the rafter that is forming
the parallelogram
(only true if the pitch of the roof is identical and the angles on the hip roof are 90
degrees)
10. Do you round when removing a roof
ANS No, removal is always the exactnumber
11. What calculations can you use to replace
ANS x1.10 for compositex1.15 for wood
.33 for composite
.25 for wood
12. "drop and roll"
ANS the method for estimating carpet
